Description

La présente invention se rapporte à un filtre plus particulièrement utilisé pour des cafetières présentant un corps cylindrique pourvu d'un couvercle percé d'un trou central dans lequel est guidée et coulisse une tige solidaire d'un piston mobile dans le corps et perméable aux liquides, ledit piston constituant un filtre.The present invention relates to a filter more particularly used for coffee makers having a cylindrical body provided with a cover pierced with a central hole in which is guided and slides a rod secured to a piston movable in the body and permeable to liquids , said piston constituting a filter.

Le corps de telles cafetières est généralement en verre et logé dans un support muni d'une anse. Du fait du matériau utilisé pour former le corps, on est obligé de prévoir des tolérances relativement importantes et le filtre doit pouvoir coulisser librement en absorbant les différences de forme de la paroi interne du corps sans laisser passer le café qui est constitué par une poudre très fine.The body of such coffee makers is generally made of glass and housed in a support provided with a handle. Due to the material used to form the body, it is necessary to provide relatively large tolerances and the filter must be able to slide freely by absorbing the differences in shape of the internal wall of the body without letting through the coffee which is constituted by a very powder fine.

Les impératifs ont par conséquent, nécessité la réalisation d'un filtre complexe et cher qui est constitué de plusieurs parties qui doivent être démontées pour le nettoyage.The imperatives have therefore required the production of a complex and expensive filter which consists of several parts which must be dismantled for cleaning.

L'un des buts de la présente invention est de réaliser un filtre plus simple à fabriquer, et par conséquent, moins onéreux que les filtres de la technique connue, tout en assurant un parfait fonctionnement.One of the aims of the present invention is to provide a filter which is simpler to manufacture and therefore less expensive than filters of the known technique, while ensuring perfect functioning.

Le filtre, selon l'invention, est destiné à être utilisé avec une cafetière du type présentant un corps cylindrique, un couvercle percé d'un trou de guidage dans lequel coulisse une tige destinée à être fixée à une noix d'un piston mobile dans le corps et constituant un filtre, ledit piston comprenant un élément filtrant tel qu'une toile métallique ou synthétique enserré entre deux disques ajourés rigides, au moins une pièce circulaire ajourée appliquée contre l'élément filtrant et dont le bord incliné est découpé pour présenter des languettes élastiques, lesdits disques ajourés étant réalisés par moulage de manière à inclure la pièce métallique circulaire pourvue de languettes élastiques et l'élément filtrant, ledit filtre étant caractérisé en ce que l'élément filtrant présente un rebord incliné avec lequel coopèrent les languettes élastiques, les disques ajourés rigides étant moulés de manière à laisser libre le rebord et les languettes élastiques.The filter according to the invention is intended for use with a coffee maker of the type having a cylindrical body, a cover pierced with a guide hole in which slides a rod intended to be fixed to a nut of a piston movable in the body and constituting a filter, said piston comprising a filtering element such as a metallic or synthetic fabric sandwiched between two rigid perforated discs, at least one circular perforated part applied against the filtering element and whose inclined edge is cut to present elastic tongues, said perforated discs being produced by molding so as to include the circular metal part provided with elastic tongues and the filter element, said filter being characterized in that the filter element has an inclined rim with which the elastic tongues cooperate, the rigid perforated discs being molded so as to leave the rim and the elastic tabs free.

Grâce à cette disposition, on réalise un filtre en une seule pièce dont les bords parfaitement souples et élastiques assurent un bon glissement le long de la paroi interne du corps cylindrique en épousant les moindres inégalités et tout en s'opposant au passage de la poudre.Thanks to this arrangement, a filter is produced in a single piece, the perfectly flexible and elastic edges of which ensure good sliding along the internal wall of the cylindrical body while marrying the least inequalities and while opposing the passage of the powder.

De préférence, les languettes élastiques affectent la forme d'un T et sont terminées par un renflement.Preferably, the elastic tabs assume the shape of a T and are terminated by a bulge.

Suivant une caractéristique constructive particulière, la noix comporte sur sa face opposée à celle destinée à être fixée à la tige un téton destiné à traverser la toile et à être fixé à une bague disposée du côté de l'autre face de la toile et ladite noix étant pourvue de branches radiales dont les extrémités libres sont solidaires d'un anneau constituant l'un des disques ajourés et destiné à porter contre la face correspondante de la pièce circulaire ajourée pourvue des languettes en forme de T, celle-ci étant conformée pour présenter un anneau sensiblement de même diamètre interne que l'anneau solidaire des branches, et le second disque ajouré étant constitué par un anneau complémentaire de même diamètre interne que les deux autres anneaux.According to a particular constructive characteristic, the nut has on its face opposite to that intended to be fixed to the rod a stud intended to pass through the canvas and to be fixed to a ring arranged on the side of the other face of the canvas and said nut being provided with radial branches, the free ends of which are integral with a ring constituting one of the perforated discs and intended to bear against the corresponding face of the perforated circular part provided with T-shaped tongues, the latter being shaped to present a ring substantially of the same internal diameter as the ring secured to the branches, and the second perforated disc being constituted by a complementary ring of the same internal diameter as the other two rings.

Grâce à cette disposition, la surface de toile filtrante est très importante ce qui facilite l'enfoncement du piston dans le corps de la cafetière.Thanks to this arrangement, the surface of the filter cloth is very large, which facilitates the insertion of the piston into the body of the coffee maker.

Suivant encore une autre caractéristique, la face de l'anneau destinée à coopérer avec l'anneau pourvu de languettes élastiques et la face de la noix pourvue du téton sont situées dans un même plan, les branches radiales étant décalées en hauteur par rapport à ce plan. Ainsi, on réalise un filtre parfaitement plan, la surface filtrante étant importante et le nettoyage est facile.According to yet another characteristic, the face of the ring intended to cooperate with the ring provided with elastic tongues and the face of the nut provided with the stud are located in the same plane, the radial branches being offset in height relative to this plan. Thus, a perfectly flat filter is produced, the filtering surface being large and cleaning is easy.

De préférence, les branches radiales ont une section en forme de T.Preferably, the radial branches have a T-shaped section.

Enfin, l'anneau complémentaire comporte sur sa face destinée à être tournée du côté de la toile des tétons, l'anneau pourvu des languettes élastiques présentant des crans correspondants et la face correspondante de l'anneau solidaire des extrémités libres des branches présentant des trous de réception des tétons. On peut ainsi prédisposer les différents éléments et les fixer par soudure à chaud ou aux ultrasons.Finally, the complementary ring has on its face intended to be turned towards the side of the nipple fabric, the ring provided with elastic tongues having corresponding notches and the corresponding face of the ring secured to the free ends of the branches having holes receiving nipples. We can thus predispose the different elements and fix them by hot welding or ultrasound.

L'invention va maintenant être décrite avec plus de détail en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :

  • Figure 1 est une vue en perspective éclatée d'un filtre, selon l'invention,
  • Figure 2 est une vue en coupe par un plan passant par l'axe du filtre.
The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:
  • FIG. 1 is an exploded perspective view of a filter according to the invention,
  • Figure 2 is a sectional view through a plane passing through the axis of the filter.

Le filtre représenté aux figures comprend une première pièce 1 présentant une noix centrale 3 dans laquelle est noyé un écrou 2 dont le taraudage 4 s'ouvre sur la face supérieure, tandis que la face inférieure est pourvue d'un téton central 5.The filter shown in the figures comprises a first part 1 having a central nut 3 in which is embedded a nut 2 whose tapping 4 opens on the upper face, while the lower face is provided with a central stud 5.

La noix 3 est solidaire de quatre branches radiales 6 dont les extrémités libres sont solidaires d'un anneau 7. Chaque branche 6 a une section en T et s'étend depuis le bord supérieur de la noix 3 vers le bord supérieur de l'anneau 7, ce dernier par son bord inférieur étant situé dans le même plan que le bord inférieur de la noix 3.The nut 3 is secured to four radial branches 6 whose free ends are secured to a ring 7. Each branch 6 has a T-section and extends from the upper edge of the nut 3 to the upper edge of the ring 7, the latter by its lower edge being situated in the same plane as the lower edge of the nut 3.

L'anneau 7 comporte, régulièrement décalés angulairement des trous 8 s'ouvrant sur sa face inférieure.The ring 7 comprises, regularly angularly offset holes 8 opening on its underside.

Le filtre comporte une toile 12 par exemple une toile métallique à mailles fines, ou une toile en matière synthétique 15 présentant un bord incliné 16.The filter comprises a fabric 12, for example a fine mesh metal fabric, or a synthetic fabric fabric 15 having an inclined edge 16.

Contre la tcile 15 vient s'appliquer un anneau 10 de préférence en acier revêtu et qui comporte une série de languettes périphériques 13 affectant chacune, la forme d'un T, l'extrémité libre de chaque languette comportant la barre du T.Against the tcile 15 is applied a ring 10 preferably of coated steel and which comprises a series of peripheral tabs 13 each affecting, the shape of a T, the free end of each tab comprising the bar of the T.

Les languettes 13 sont inclinées de manière à épouser le bord 16 de la toile.The tongues 13 are inclined so as to match the edge 16 of the fabric.

L'anneau 10 présente le long de son bord interne des crans 11 régulièrement décalés angulairement pour coïncider avec les trous 8.The ring 10 has notches along its internal edge 11 regularly angularly offset to coincide with the holes 8.

Il est prévu un anneau 18 présentant sur une face des tétons 19 destinés à venir coopérer avec les crans 11 et à s'engager dans les trous 8.There is provided a ring 18 having on one face studs 19 intended to cooperate with the notches 11 and to engage in the holes 8.

Le téton 5 est destiné à s'engager dans le trou 21 d'une bague 20, ledit trou 21 étant terminé par un évasement 22 destiné à permettre de recevoir une tête formée par écrasement ou déformation à chaud du téton 5.The stud 5 is intended to engage in the hole 21 of a ring 20, the said hole 21 being terminated by a flare 22 intended to allow a head formed by crushing or hot deformation of the stud 5 to be received.

Comme on le voit aux différentes figures, sur la face de l'anneau 18 pourvue de tétons 19 la toile 15 est posée, l'anneau 10 étant posé sur ladite toile 15 et la pièce 1 venant reposer sur l'anneau 10 par son anneau 7, les tétons 19 s'engageant dans les trous 8, tandis que le téton 5 traverse la toile 15 et s'insère dans le trou 21 de la bague 20.As can be seen in the various figures, on the face of the ring 18 provided with pins 19 the fabric 15 is placed, the ring 10 being placed on said fabric 15 and the part 1 coming to rest on the ring 10 by its ring 7, the studs 19 engaging in the holes 8, while the stud 5 crosses the fabric 15 and is inserted in the hole 21 of the ring 20.

Les anneaux 18 et 7 sont soudés à la chaleur ou aux ultrasons et ainsi on réalise un filtre monobloc.The rings 18 and 7 are welded with heat or ultrasound and thus a monobloc filter is produced.

Etant donné que les branches 6 sont éloignées de la toile 15 la surface filtrante est largement dimensionnée.Since the branches 6 are distant from the fabric 15 the filtering surface is largely dimensioned.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
